Complete Session and NTVDM Cleanup

UTS Complete Session Cleanup

The Georgia SoftWorks UTS for Windows provides features that ensure that all SSH2/Telnet sessions are properly terminated, even during abnormal client and link failures. Many internal session cleanup methods are automatic; others are configurable using the different Inactivity and Heartbeat timers, termination strings and scripts. Properly terminating telnet sessions ensure that all sessions are available for use and that problems do not accumulate over a long term.

The Georgia SoftWorks Universal Terminal Server has employed very complex and sophisticated proprietary algorithms to detect, identify and eliminate “orphaned” NTVDM’s [18] directly initiated by applications when using SSH2/Telnet. In many cases orphaned NTVDM’s or processes can consume all of the server’s processing power rendering the server crippled or useless. Realizing that NTVDM cleanup is essential in industrial, commercial and mission critical applications, a great amount of design and development resources were expended to ensure proper operation in this area
